Let's divide 57120462 by 31
The aim is to understand the frequency of 31 in 57120462.

On to step 1:
The number 31 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 31

Moving on to step 2:
31 can be fit into 57 1 times, resulting in a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 26 after subtracting 31 from 57.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 31

Let's proceed to step 3:
31 can be fit into 261 8 times, resulting in a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 248 from 261 leaves us with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 31

Advancing to step 4:
31 can be fit into 132 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 184.0
Subtract 124 from 132 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 31

Moving on to step 5:
If we divide 80 by 31, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1842.0
Deduct 62 from 80 and we're left with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 31

Step 6:
31 goes into 184 5 times with a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 18425.0
Subtracting 155 from 184 leaves us with 29.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 31

Moving on to step 7:
31 can be fit into 296 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 184259.0
If we subtract 279 from 296, we get 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 31

Going ahead to step 8:
The number 31 fits into 172 5 times, leaving a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 1842595.0
Subtracting 155 from 172 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 31 fits into 170 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 1842595.5
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
150 divided by 31 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1842595.54
If we subtract 124 from 150, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
31 goes into 260 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 1842595.548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
When dividing 120 by 31, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 1842595.5483
Deduct 93 from 120 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
If we divide 270 by 31, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 1842595.54838
If we take 248 away from 270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
When dividing 220 by 31, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 1842595.548387
If we subtract 217 from 220, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 15:
The number 31 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 1842595.548387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 16:
If we divide 300 by 31, we get 9 and a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 1842595.54838709
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 1842595.54838709 with a balance of 2.1e-08.
